The Clustering Properties of Lyman–break Galaxies at Redshift
We present a new measure of the angular two–point correlation function of Lyman–break galaxies (LBGs) at z ∼ 3, obtained from the variance of galaxy counts in 2–dimensional cells. By avoiding binning of the angular separations, this method is significantly less affected by shot noise than traditional measures, and allows for a more accurate determination of the correlation function. We used a s...
متن کاملCO line emission from Lyman break galaxies
Context. The detection of the rotational lines of CO in proto-galaxies in the early Universe provides one of the most promising ways of probing the fundamental physical properties of a galaxy, such as its size, dynamical mass, gas density, and temperature. While such observations are currently limited to the most luminous galaxies, the advent of ALMA will change the situation dramatically, resu...
متن کاملLyman Break Galaxies in the NGST Era
With SIRTF and NGST in the offing, it is interesting to examine what the stellar populations of z ≈ 3 galaxies models imply for the existence and nature of Lyman-break galaxies at higher redshift. To this end, we “turn back the clock” on the stellar population models that have been fit to optical and infrared data of Lymanbreak galaxies at z ≈ 3 . The generally young ages (typically 108±0.5 yr)...
متن کاملSpitzer View of Lyman Break Galaxies
Using a combination of deep MID-IR observations obtained by IRAC, MIPS and IRS on board Spitzer we investigate the MID-IR properties of Lyman Break Galaxies (LBGs) at z∼3, establish a better understanding of their nature and attempt a complete characterisation of the population. With deep mid-infrared and optical observations of ∼1000 LBGs covered by IRAC/MIPS and from the ground respectively, ...
متن کاملLyman-break galaxies: are they young spheroids?
We have compared the results from a model for the chemical evolution of an elliptical galaxy with initial luminous mass of 2 ·10M⊙ and effective radius of 2 kpc with the recent abundance determinations for the Lyman-break galaxy MS 1512-cB58 at a redshift z=2.7276. After correcting the iron abundance determination for the presence of dust we concluded that the observed [Si/Fe], [Mg/Fe], [N/Fe] ...
